Abstract
A new polyfunctional extractant, 1,3-bis[((hydroxyphenylphosphinyl)acetyl(hexyl)amino)methyl]benzene, has been synthesized. The extraction of REE(III) ions from nitric acid media by solutions of this extractant in organic solvents has been studied. The stoichiometry of the extracted complexes has been determined. The effect of the nature of the organic diluent and the concentration of HNO3 in the aqueous phase on the efficiency of metal ion extraction into the organic phase has been considered. The extraction capacity of bis(N-hexylcarbamoylmethyl)phenylphosphinic acid based on m-xylylenediamine in relation to REE(III) ions is significantly higher than that of its mono analogue, (N,N-dibutylcarbamoylmethyl)phenylphosphinic acid.
期刊介绍：
Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
